C-MOS 3-TERMINAL POSITIVE VOLTAGE REGULATOR

Japan Radio Corporation  

NJU7201 Series

C-MOS 3-TERMINAL POSITIVE VOLTAGE REGULATOR

■ GENERAL DESCRIPTION

The NJU7201 series is a C-MOS 3-terminal positive voltage

regulator which contains internal accurate voltage reference, error

amplifier, control transistor and output voltage setting resistor.

The regulation voltage is fixed by internal circuits and the following

line-up of different output voltage versions are available.

The NJU7201 series is suitable for battery operated items and

battery back-up systems because of low operating current and low

dropout voltage.

■ FEATURES

• Low Operating Current

(19μA typ.)

• Wide Operating Voltage Range

• Low Dropout Voltage

(ΔVIO < 0.3V 1.2 to 1.5V output, IOUT = 0.5mA)

(ΔVIO < 0.6V 2.5 to 3.5V output, IOUT = 20mA)

(ΔVIO < 0.6V 4.0 to 5.5V output, IOUT = 40mA)

• Small Temperature Coefficient of Output Voltage

• Package Outline

(SOT-89)

• C-MOS Technology
